Application entity resource creation and registration method, communication node device and terminal device

Abstract

A method for creating a resource for an application entity, a method for registering an application entity, a communication node device, and a terminal device, the method for creating a resource for an application entity includes: receiving a registration request sent by the application entity when the application entity is switched from a first communication link to a second communication link; creating a resource as a first resource on the basis of the registration request; assigning an identifier corresponding to the first resource to the application entity, such that the application entity is associated with the first resource.

What is claimed is: 
     
       1. A method for creating a resource for an application entity, comprising:
 receiving a registration request sent from the application entity when the application entity is switched from a first communication link to a second communication link; 
 creating a resource according to the registration request as a first resource; and 
 assigning an identification corresponding to the first resource to the application entity so as to associate the application entity with the first resource, 
 wherein the first resource comprises an attribute indicating availability of the first resource associated with the application entity, which serves as a first attribute, and the value of the first attribute is set to indicate that the first resource is available or unavailable. 
 
     
     
       2. The method according to  claim 1 , wherein receiving the registration request sent from the application entity comprises: receiving, on the second communication link, the registration request sent from the application entity. 
     
     
       3. The method according to  claim 1 , wherein creating the first resource comprises setting the first attribute to indicate that the first resource is available; and
 wherein when the application entity is switched from the second communication link back to the first communication link, 
 the first attribute is set to indicate that the first resource is unavailable. 
 
     
     
       4. The method according to  claim 1 , wherein when the application entity is switched from the second communication link back to the first communication link,
 the first resource associated with the application entity is deleted. 
 
     
     
       5. The method according to  claim 1 , wherein prior to receiving the registration request sent from the application entity, the method further comprises:
 receiving a resource acquisition request sent from the application entity, and acquiring a resource based on an identification corresponding to a resource created for the application entity included in the resource acquisition request as a second resource. 
 
     
     
       6. The method according to  claim 5 , further comprising:
 before the application entity is switched from the second communication link back to the first communication link, setting an attribute indicating availability of the second resource to cause the second resource to be unavailable. 
 
     
     
       7. The method according to  claim 6 , further comprising:
 when the application entity is switched from the second communication link back to the first communication link, setting an attribute indicating availability of the second resource to indicate that the second resource is available. 
 
     
     
       8. The method according to  claim 5 , further comprising:
 after acquiring the second resource, deleting the second resource. 
 
     
     
       9. The method according to  claim 5 , wherein the identification corresponding to the second resource is specified by the application entity or automatically assigned for the application entity; and wherein the identification corresponding to the second resource is globally unique or locally unique. 
     
     
       10. The method according to  claim 1 , wherein the registration request comprises a start identifier indicating to create the first resource for the application entity. 
     
     
       11. A communication node device for implementing the method of  claim 1 . 
     
     
       12. A method for registration of an application entity, comprising:
 sending a registration request to create a resource as a first resource when the application entity is switched from a first communication link to a second communication link; and 
 associating the application entity with the first resource based on an identification corresponding to the created first resource, 
 wherein the first resource comprises an attribute indicating availability of the first resource associated with the application entity, which serves as a first attribute, and the value of the first attribute is set to indicate that the first resource is available or unavailable. 
 
     
     
       13. The method according to  claim 12 , wherein sending the registration request comprises sending the registration request on the second communication link. 
     
     
       14. The method according to  claim 12 , wherein when the application entity is switched from the second communication link back to the first communication link,
 a request for resetting the first attribute is sent to cause the first resource to be unavailable. 
 
     
     
       15. The method according to  claim 12 , wherein when the application entity is switched from the second communication link back to the first communication link,
 a request for deleting the first resource associated with the application entity is sent. 
 
     
     
       16. The method according to  claim 12 , wherein prior to sending the registration request, the method further comprises sending a resource acquisition request to acquire a second resource created for the application entity;
 after acquiring the second resource, the method further comprises sending a request for resetting a second attribute indicating availability of the second resource to cause the second resource to be unavailable. 
 
     
     
       17. The method according to  claim 16 , wherein
 when the application entity is switched from the second communication link back to the first communication link, the method further comprises sending a request for setting the second attribute indicating availability of the second resource to cause the second resource to be available; 
 after acquiring the second resource, the method further comprises sending a request to delete the second resource. 
 
     
     
       18. A terminal device for implementing the method of  claim 12 .
